It is believed by the author that a classification and presentation of selected groups of the devices produced in the past by which it was by the inventor believed, self-motive power had been attained, will save much work in fields already thoroughly exploited.

So far as the author knows no book on the subject has appeared since 1870. The various encyclopedias published contain articles on the subject, but they are necessarily brief, and not satisfying to young men who have become interested ...

It is intended to have the first sixteen pages of this book simply read in the class, with such running comment and discussion as may be useful to help the beginner catch the spirit of the subject-matter, and not leave him to the mere letter of dry definitions. In like manner, the definitions at the beginning of each Book should be read and discussed in the recitation room.

There is a decided advantage in having the de_nitions for each Book in a single group so that they can be included in on...

The translation by Constance Garnett from the original Russian is widely regarded as a reference. Garnett translated seventy volumes of Russian prose for publication, including all of Dostoyevsky's novels. Dostoyevsky's works of fiction include 17 short stories, in this edition included wonderful stories that we published:

– AN HONEST THIEF,

– A NOVEL IN NINE LETTERS,

– AN UNPLEASANT PREDICAMENT,

– ANOTHER MAN'S WIFE OR THE HUSBAND UNDER THE BED,

– THE HEAVENLY CHRISTMAS T...

It is impossible to understand principles without some statement of theory; and a book in order to be practical must therefore be to some extent theoretical. I have been as concise and brief in the theoretical parts as clearness would permit of, and I trust they are not out of proportion to the practical parts.

Either to paint well, or to judge well of a painting, requires an understanding of the same things: namely, the theoretical standpoint of the painter; the technical problems of color, ...

THE modest dimensions of this book are perhaps sufficient indication that it is not intended as an aid to the collector. There are about five hundred and fifty known species of spiders in the United Kingdom alone, and at least an equal number of pages would be needed to describe them.

There are certain days of the year when the immense wealth of spider industry going on all around us is revealed in a way calculated to strike even the least observant. We all know—and derive no peculiarly ple...

The Aeneid is widely considered Virgil's finest work and one of the most important poems in the history of western literature. Virgil worked on the Aeneid during the last eleven years of his life (29–19 BC), commissioned, according to Propertius, by Augustus. The epic poem consists of 12 books in dactylic hexameter verse which describe the journey of Aeneas, a warrior fleeing the sack of Troy, to Italy, his battle with the Italian prince Turnus, and the foundation of a city from which Rome ...

The “Manifesto of the Communist Party” was written by Marx and Engels as the Communist League’s programme on the instruction of its Second Congress (London, November 29-December 8, 1847), which signified a victory for the followers of a new proletarian line during the discussion of the programme questions.

When Congress was still in preparation, Marx and Engels arrived at the conclusion that the final programme document should be in the form of a Party manifesto (see Engels’ letter ...

In studying these Lessons please remember 3 points:—

1. Not one useless or superfluous sentence is written. Every word is full of meaning. They are highly condensed. Think deeply over them.

2. They are meant as a practical supplement to the 'Spiritual Consciousness,' 'Soul-Force' and 'Inner Forces.' Studied side by side, these lessons will yield a great deal of benefit. You are expected to think hard and long.

3. Let none expect speedy or miraculous results. All spiritual training calls for...

It is an acknowledged fact that we perceive errors in the work of others more readily than in our own.

In this Beginner's Psychology I have tried to write, as nearly as might be, the kind of book that I should have found useful when I was beginning my own study of psychology. That was nearly thirty years ago; and I read Bain, and the Mills, and Spencer, and Rabier, and as much of Wundt as a struggling acquaintance with German would allow. Curiously enough, it was a para...

Theodore Roosevelt had the good fortune to be born of a well-known, long-established family, with every facility for education and with an atmosphere of patriotism and disinterested service both to country and humanity all about him. In his father he had before him an example of lofty public spirit, from which it would have been difficult to depart.

But if the work of his ancestors relieved him from the hard struggle which meets an unaided man at the outset, he also lacked the spur of necessi...
